Abstract

DISPOSITIVO DE AMORTIGUACION DE VIBRACION CONOCIDO PARA EL SOPORTE DESDE ABAJO DEL MONTAJE DE CUBO Y TAMBOR EN UNA MAQUINA DE LAVAR ROPA COMPRENDE UNA ENVOLTURA Y UN EMBOLO QUE SE DESLIZA EN ELLO, LOS EXTREMOS LIBRES DE LA ENVOLTURA Y EL EMBOLO SIENDO GIRATORIAMENTE CNECTADAS A UNA PARTE ESTACIONARIA DE LA MAQUINA Y UNA PARTE MAS BAJA DEL MONTAJE DE CUBO Y TAMBOR, RESPECTIVAMENTE. LA ENVOLTURA Y EL EMBOLO ESTAN USUALMENTE INSEPARABLE UNO DEL OTRO, TAL QUE EL MONTAJE DEL DISPOSITIVO SE DIFICULTA Y ACTIVE UN NUMERO DE OPERACIONES MANUALES. CUANDO EL DISPOSITIVO ES HECHO DE UN MATERIAL TERMOPLASTICO, EL CALOR DE FRICCION GENERADO ENTRE EL EMBOLO Y LA ENVOLTURA PUEDE CAUSAR AL ULTIMO A SER DEFORMADO, RESULTANDO EN UNA PERDIDA DE LA EFICIENCIA DE AMORTIGUACION DE VIBRACION. ACORDE AL INVENTO, LA ENVOLTURA DEL DISPOSITIVO DE AMORTIGUACION DE VIBRACION ESTA FORMADA COMO UN CILINDRO METALICO AJUSTADAMENTE ENCERRADO EN UNA ESTRUCTURA SOPORTE DE UN MATERIAL PLASTICO PREFERIBLEMENTE MOLDEADO DE INYECCION SOBRE ELLO. LAS PARTES DE EXTREMO LIBRE DE LA ESTRUCTURA SOPORTE Y DEL EMBOLO, EL ULTIMO SIENDO DEL MISMO MODO UN MIEMBRO PLASTICO, SON FORMADOS CON MEDIOS QUE PERMITEN SER GIRATORIAMENTE CONECTADOS A LAS PARTES QUE MONTAN RESPECTIVAS POR LA INSERCION DE PERNOS O LOS SIMILARES EN UNA OPERACION AUTOMATIZADA COMPLETAMENTE.
